That's what I thought. So the sweet spot here seems to be the 3055.

Definitely.  For the price difference, I think it's worth it to step up to the 3055.

Is the SDM3055 discontinued? I'm starting to see it disappear? OOS on Amazon (damn, was a good price)

These items are discontinued from the TEquipment catalog and are no longer stocked at TEquipment.

No, it's still a current model.

There is sometimes confusion as it's not advertised as an X model as their release predates the X ranges of Siglent equipment. However the X model rubber bumpers are now fitted on SDM3055 so they look the same as an X model.

Correct, TQ are no longer Siglent agents and haven't been for some time.

Saelig now offer similar discounts and have a thread where you can ask for the EEVblog member discount code.

Hi,
Tautech asked me to post some pictures of the 3045X internals.

So here goes:

I'm looking to get my first bench DMM, and the Siglent ones look very tempting. However I'm also quite baffled by the pricing of the 3045X vs 3055. My main usage would be <20V, so as far as I can understand I'd get a lot more bang for just a few more bucks with the 3055.

Crap, I just a Siglent Function Generator and a Siglent 200Mhz Four Channel scope from them, through Amazon. I didn’t know to ask for an EEVBlog Forum discount 8-(

Hello everybody,

I would like to share my bad experience with the SDM3065x DMM which I got today.

It is a brand new, out of the box unit and guess what...It doesn't turn on!

Actually what it does is that it loads the boot screen with the fancy Siglent logo and stays there for ever.

I have prepared a video showing the problem and I will send it to my distributor's help center first thing tomorrow morning, asking for immediate replacement.

By the way did anyone else have the same problem?

For those interested to see the video I have a low res version in this dropbox link.

Welcome to the forum.

Oh dear that is not a good first experience.  :-//
By PM I send a link for the USB recovery package.
Unpack the ZIP file and carefully follow instructions.

Please report outcome.

Edit to add:
When recovered be sure to update the firmware to the latest version:

Hello,
I have a SDM3055 and Im very happy with it.
I bought it before Siglent release the SDM3065X.
I also have a SDG2082X.....It is so stupid but I have on the SDM3055 the old model bumpers.
Is it possible to buy and change the old bumpers by the ones from the model X ?

It will look nicer on my bench  8)

I will buy in the next few weeks a SVA1015X from Batronix, maybe with the help of Siglent, il will be possible to add those bumpers in the package ?

I also have a SDS2204X so I am unintentionally a siglent guy  ;D

Yes early SDS3055 did not have the X model bumpers but they all have them now.  :)
Siglent have not changed the SDM3055 model name to 3055X to avoid confusion.

You will need to have your supplier order the X model bumpers for you.
They should not be very expensive .......a replacement tilting bail handle I got that fits all SDM and SDG models was only a few $.

I have been in contact with Siglent Europe about your request and think the answer might be of public interest:

According to the information from the Siglent factory in Shenzhen, the new X-series bumpers do not fit the old SDM3055 models.

Siglent Europe would have been glad to help you with this, but unfortuantely it won't work.

I have an SDM3065X. And an SDG2042.

If Siglent were a normal company they would have rack mounting hardware such that my meters could be mounted side-by-side, using a total of 2U. Not so, SDG-RMK is not of this world, it's the freak show of rackmounting kits. What is it whith chinese design, or rather the lack of it? Like the new Rigol SG:s, or ... SDG-RMK.

Also, calibration documentation for SDM3065X will be finished by June ... 2035.

I’m late to this thread - just happened to be reading up on graphing DMMs....

Wow - Impressive recovery capability in the Siglent design and very impressive support by tautech!

I asked about dual rack mounts a few weeks back and forgot to post about them.......they're coming !
Dunno any time frames but suggest you keep a watch on Siglent websites for them.

Some questions about SDM3045X statistics, specifically the min/max function and memory depth.

See photo; I am doing long term (several days) monitoring of a DC voltage.  When the photo was taken I was at over one million samples and everything seemed to be working fine (ignore the ghosting in the displayed value - it's just normal flicker versus camera exposure time).

Questions:
1- What is the sample rate?  It is clearly several times per second but I can't find an actual specification in the documentation.
2- What is the maximum number of samples possible before I run out of memory?  Again, can't find this in the specs.
3- What happens when I run out of memory?  Does it flush the stored data and start over, or just stop running, or what?

Thanks for any insight you can provide.

1 - The sample rate is set by the Speed softkey (2nd softkey after pressing DCV button).  For the 3045X three  reading  rates  are  available  for  DCV,  ACV,  DCI,  ACI and  -Wire/4-Wire Resistance: “Slow”, “Middle” and “Fast”:

There is a linkage for both reading resolution and reading (measurement) rate.
5 reading/s and 50 reading/s belongs to 4.5 digit resolution.
150 reading/s belong to 3.5 digit resolution.
The  reading  resolution  of Temperature is  fixed  at 4.5  digit  and “Fast” respectively.
The  reading  resolutions  and  measurement  rates  of  both  Diode  and Continuity are fixed at 4.5 digit and “Fast” respectively.
The  reading  resolution  and  measurement  rate  of  the  Frequency function are fixed 4.5 digit and “Slow” respectively.
The reading resolution and measurement rate of the Capacitance function are fixed at 3.5 digit and “Slow” respectively.

2 - According to the manual, the sample field for triggering has a limit of 599999999.  So that's my guess for max samples.
3 - Don't know what happens when it reaches the limit; it probably starts at 0.

What's the difference between the DMMs on a schematic level? Like, do they use different references, ADC, etc?

Is there any measurements of noise (not acoustic noise, but measurement noise) and stability?

SDM3045X and 3055 are very similar and the jury is still out as to they might be the same excepting displayed digits.
However they each use different firmware which might indicate there are internal differences.
There's PCB pics of each model earlier in this thread.
SDM3065X is different and uses the LM399 Vref.

Datasheets don't tell the whole story ;).

Nice units, too bad SDM3065X costs too close to DMM6500 :(. Although, the latter is too big to fit my bench... Dilemma.
